A slope of -2 and a y-intercept of -7

Answer:

a.) terry didn't line up the triangle correctly. 4/y = 20/18

b.) (20+16)/18

Step-by-step explanation:

for part a, you have to make sure the angles line up correctly (the angle with one tick mark lining up with the angle with one tick mark, the angle with two tick marks lining up with the angle with two tick marks, etc.)

for part b.) you just put the proportional lengths of the bigger triangle in for the lengths of the smaller triangle.

Answer:

coordinates of H = (1, 0)

Coordinates of G = ( - 3.6, -2) or (5.6, -2)

Step-by-step explanation:

E(5,3) and F (2,-1) are two vertices of a square EFGH and H is in the x-axis.

Let the coordinates of H is (x, 0) and G is (a, b).

The length of side EF is

[tex]EF = \sqrt{(5 -2)^2 + (3 +1)^2} = 5[/tex]

So,

[tex]EH = \sqrt{(5 -x)^2 + (3 -0)^2} = 5\\\\(5 -x)^2+ 9 = 25\\\\5 - x = 4\\\\x = 1[/tex]

And

[tex]GH = \sqrt{(a -x)^2+ b^2} = 5\\\\(a -1)^2+ b^2 = 25\\\\a^2 + b^2 + 1 - 2 a = 25\\\\a^2 + b^2 - 2a = 24 .... (1)[/tex]

Now

[tex]FG = \sqrt{(a -2)^2+ (b +1)^2} = 5\\\\(a -2)^2+ (b+1)^2 = 25\\\\a^2 + b^2 + 2b - 2 a = 20\\ ..... (2)[/tex]

Solving (1) and (2)

b = - 2 ,

[tex]a = \frac{2 \pm\sqrt{4 + 80}}{2}\\\\a = \frac{2 \pm 9.2}{2}\\\\a = - 3.6, 5.6[/tex]

Answer:

2/15

Step-by-step explanation:

I think not 100% on this but not so sure-

Subtract 5 1/10 from 5 3/4

5 3/4 - 5 1/10

• Subtract the whole numbers (5 and 5)

5 - 5 = 0

• LCM of the denominators (4 and 10)

= 13/20

She put an extra 13/20

Answer:

Step-by-step explanation:

this is a question about two similar triangles  , one is from  Amelia , the other is the tree.

Given:

Principal value = $8,008

Rate of interest = 2% compounded 6 times per year.

Time = 16 years

To find:

The account balance after 16 years.

Solution:

The formula for amount is:

[tex]A=P\left(1+\dfrac{r}{n}\right)^{nt}[/tex]

Where, P is principal, r is the rate of interest, n is the number of times interest compounded in an year and t is the number of years.

Putting [tex]P=8,008, r=0.02,n=6,t=16[/tex] in the above formula, we get

[tex]A=8008\left(1+\dfrac{0.02}{6}\right)^{6(16)}[/tex]

[tex]A=8008\left(\dfrac{6.02}{6}\right)^{96}[/tex]

[tex]A=11022.1721148[/tex]

[tex]A\approx 11022.17[/tex]

Therefore, the account balance after 16 years is $11022.17.

Answer:

Please find attached sketch of the path of the ball, having plot area and plot points, created with MS Excel

Step-by-step explanation:

Question;

The equation representing the path of the ball obtained from a similar question posted online are;

h₁ = -4·(t + 1)·(t - 5), h₂ = -4·(t - 2)² + 36, h₃ = -4··t² + 16·t + 20

The above equations represent the same path

The equation, h₁ = -4·(t + 1)·(t - 5), gives the roots of the height function, h(t), used in determining the height of the ball after time t

At (t + 1) = 0 (t = -1) or at (t - 5) = 0 (t = 5), the ball is at ground level

The ball reaches the ground, is at ground level at t = 1, and at t = 5 seconds after being tossed, where h(t) = 0

The equation of the path of the ball in vertex form, y = a·(x - 2)² + k, is h₂ = -4·(t - 2)² + 36, where, by comparison, we have;

The vertex of the ball = The maximum height reached by the ball  = (h, k) = (2, 36)

The coefficient of the quadratic term, t², is negative, therefore, the shape of the parabola is upside down, ∩, shape

The sketch of the path of the ball created with MS Excel, used in plotting the vertex, the initial value and the root points of the parabola, through which the ball passes and joining of the points with a 'smooth' curve is attached

Answer:

[tex]y = \boxed0[/tex]

Step-by-step explanation:

we are given a sin function

[tex] \displaystyle h(x) = - 4 \sin(x -\pi /4) [/tex]

we want to figure out the midline of the function graphically The midline of a sinusoidal function is the horizontal line that passes exactly in the midline of its extreme value however since we a function recall that,

[tex] \displaystyle f(x) = a \sin(bx -c) + d[/tex]

where the midline is

to figure out the midline rewrite the function

[tex] \displaystyle h(x) = - 4 \sin(x -\pi /4) + 0[/tex]

therefore the midline is

[tex]y = \boxed0[/tex]

Answer:

36 units squared

Step-by-step explanation:

10 times 10 - 4 times 4  = 100-16 = 84, take the square root of 84 = 9.12 which rounds to 9, now that we found the height, we use the area of a triangle formula, A=bh/2, so the base is 8 times height 9 = 72 divided by 2 = 36

Answer:

Answer:

$5472

Step-by-step explanation:

Set up a reverse ratio for each change:

4446/x = 65/100

65x = (4446) x (100)

65x = 444,600

x = 6840

Before her salary was reduced by 35%, she was earning $6840.

x/6840 = 20/100

100x = (6840)(20)

100x = 136,800

x = 1368 = 20%

$6840 - $1368 = $5472

Answer:

x = 78

Step-by-step explanation:

We can find angle y

D + B + y = 180 since the sum of the angles of a triangle are 180

31+47+ y =180

78+y = 180

y = 180 - 78

y = 102

x+y = 180 since they form a straight line

x + 102 = 180

x = 180-102

x = 78

[tex]\boxed{\large{\bold{\blue{ANSWER~:) }}}}[/tex]

we have to find the value of the x°=<GHC

In the triangle BDH,

we know that,

Sum of three angle of a triangle is 180°

According to the question,

But,

<GHC and <BHD forms a straight line

so,

Therefore,

The value of x is 78°

3 is the missing value

Step-by-step explanation:

Given

[tex]24 + 12 = \_ * (8 + 4)[/tex]

Required

Complete the blank

The model is not given; but the question can still be solved.

We have:

[tex]24 + 12 = \_ * (8 + 4)[/tex]

Add 8 to 4

[tex]24 + 12 = \_ * 12[/tex]

Add 24 to 12

[tex]36= \_ * 12[/tex]

Divide both sides by 12

[tex]3= \_[/tex]

Answer:

1. Multiply by 3

2. Multiply by 1/3

Step-by-step explanation:

6x - 3y = 3

-2x + y = -14

1. In order to eliminate the x-terms, they would both have to equal the same number with opposite signs (positive and negative). Since we are only touching the second equation, how can we get from 2 to 6? We can multiply 2 by 3 to get to 6 (negative 6 in the end.) This would result as follows:

6x - 3y = 3

-6x + 3y = 42

2. In order to eliminate the y-terns through multiplying with the first equation, we have to figure out how to make 3y into 1y. We can do this by adding its reciprocal, 1/3. 1/3 × 3 = 1. This would result as follows:

2x - y = 1

Answer:

Yes Ella has enough to make 30 mince pies

Step-by-step explanation:

to make 36 mince pies you will need

400g of butter

500g of flour

300g of sugar

500g of mince meat

2 eggs

Ella has 1000g of butter

1000g of flour

500g of sugar

600g of meat

6 eggs

these ingredients are more than enough because

1000g-400g=600g-butter

1000g-500g=500g flour

500g-300g=200g sugar

600g-500g=100g mince meat

6-1= 5 eggs

if she were to follow the 36 pie recipe, which is two times the 18 pie recipe

but like  I don't know, because it says a recipe for 18 mince pies, but in the box it says 12

Answer:

[tex]\frac{9+ 5\sqrt{6} }{23}[/tex]

Step-by-step explanation:

2√3 + 3√2 *   4√3 -√2

4√3 +√2          4√3 -√2

multiply by conjugate

2√3 + 3√2 *   4√3 -√2      =       18 +10√6   = 9 +5√6  

4√3 +√2          4√3 -√2                   46                   23

Answer:

Step-by-step explanation:

To rationalize the denominator, multiply the numerator and denominator by the conjugate of the denominator.

Conjugate of 4√3 + √2 is 4√3 - √2

(2√3 +3 √2)(4√3 - √2) = (2√3 * 4√3) - (2√3*√2) + (3√2*4√3) -(3√2*√2) {Use FOIL method}

= 8*3 - 2*√6+12√6 -3*2

= 24 -2√6 +12√6 - 6

= 24 - 6 + (-2+12)√6)

= 18 + 10√6

Step-by-Step Explanation:

You can mark out B and C because the amount of money they spend has to be less or equal to the amount of money they have.

A is wrong because we already know the total price for the movies. We know the price of the games are $43 each. X is the amount of game she can afford to get.

So in conclusion, D is the correct answer.
